1. The human civilization underwent many changes and developments with the passage of time. Early man lived in caves and forests. They lived on the food available in the forests. Science has blessed mankind with all the basic comforts of life. Man started living in cities. Cities became the major centers of live hood. A city has larger population compared to a town and a village.

Life is full of activities in a big city. A big city is a centre of all types of education. It is a centre of trade, medical facilities, business and recreation. The population increase during the daytime. People staying the nearby villages and towns come to the city on different errands.

Life in a big city starts early in the morning. many school buses carrying school children can be seen playing on roads. School children dressed in their uniform can be seen on the roads walking or waiting for buses. Some are seen moving on scooters and in cars. Then a long queue of office-workers can be seen at the bus stops. Some go by their own vehicles and others go by buses or trains. Some people use cycles and auto rickshaws to go to their destination. People flock to the market to buy vegetables and household goods. With every passing hour, the traffic goes on increasing. The shops and the market places remain crowded till the evening hours.

Life in the city has certain charms. There are many places for recreation. There are big parks, hotels and clubs for entertainment. There are discotheques for music lovers and party-goers.

2. Ha Long Bay is one of the seven natural wonders in the world. Ha Long Bay is located in Quang Ninh province which is in the north of Vietnam. It is nearly 200km from Hanoi. So it takes you about 4 hours by car. You can also travel there in a coach or even in a helicopter on Saturday. The best season to visit Ha Long is in summer when the weather is warm and sunny. Ha Long Bay has many beautiful caves and islands; therefore, you must take a boat trip to enjoy the view here. You certainly must take pictures to remember the trip better, too. If you are an active person, you must do the water sports here like swimming, sailing, and windsurfing. One more thing, you must try the seafood here because it is incredibly fresh and delicious. With this travel guide, I hope that you will have a wonderful time here in the number one natural wonder of Vietnam.

3.There are many environmental issues facing Vietnam. In your opinion, what are the causes and effects of the biggest environmental issue that Vietnam must confront?

Vietnam has been a developing country that has had a high speed of economic growth because of industrialization. The development brings many benefits for Vietnamese society, but it also causes some serious environmental problems.

Specifically, to perform the industrialization, there have been more businesses, factories and industrial areas being created, and the activities of these businesses contribute to significant pollution of air, land and water. In a sustained effort to change the domestic economic structure and develop the economy, the Vietnamese government has encouraged improvement of industry. This means the activities of factories and industrial areas have increased at a high level.

As a result, there are more and more fossil fuels being burned and a large amount of carbon dioxide, carbon monoxide and nitrogen put into the air, land and water. This causes the serious pollution of the air, land and water in Vietnam's environment. For example, there are many polluted rivers in Vietnam with black water and a terrible smell, and the Saigon River is a significant example. Furthermore, there are many places that do not have fresh water to drink and use for basic demands because of the pollution of water sources that result from the industrial waste of many factories.

In my opinion, the best solution for this problem is improving the environmental awareness of people by a suitable education program that can educate people about the importance and essential role of the environment. In addition, the government should have more heavy penalties for any action that does not follow the law and harms nature. If there is effective cooperation between people and organizations, the environment will get better in the near future.

1, I don't like living in the city for a number of reasons. In the city there is a lot of smoke and dust emitted from factories, causing serious air pollution. Life here is very busy and busy. The road is always busy, at rush hour is always congested. In the city there are not too many trees because there is no vacant land. But in the city, there are also many convenient spots. You can go anywhere quickly and easily. The cuisine here is also diverse with many delicious dishes.
